We investigated the effect of "psyching-up" on force production during the bench press. Twelve men (mean age +/- SD: 27.4 +/- 11.2 years) and 8 women (20.9 +/- 2.5 years) with strength-training experience performed 5 bench press repetitions on a modified Biodex isokinetic dynamometer during 3 interventions. The interventions were counterbalanced and included a free-choice psych-up, a cognitive distraction, and an attention-placebo. Peak force recorded after psyching-up (mean +/- SD: 764 +/- 269 N.m) was significantly different from both distraction (703 +/- 282 N.m, p = 0.003) and attention-placebo (708 +/- 248 N.m, p = 0.01). The mean percentage increase in peak force from distraction to psyching-up was 11.8% (6 to 18%, 95% confidence interval [CI]) and 8.1% from placebo to psyching-up (3 to 13%, 95% CI). The results of the present study indicate that psyching-up may increase force production during the bench press exercise in participants with at least 1 year strength-training experience.
我们研究了“心理准备”对卧推过程中力量产生的影响。12名男性(平均年龄±标准差:27.4±11.2岁)和8名有力量训练经验的女性(20.9±2.5岁)在3种干预措施下,在改良的Biodex等速测力计上进行5次卧推重复动作。这些干预措施进行了平衡处理,包括自由选择的心理准备、认知分散注意力和注意力安慰剂。心理准备后记录的峰值力量(平均±标准差:764±269牛·米)与分散注意力(703±282牛·米,p = 0.003)和注意力安慰剂(708±248牛·米,p = 0.01)均有显著差异。从分散注意力到心理准备,峰值力量的平均百分比增加为11.8%(6%至18%,95%置信区间[CI]),从安慰剂到心理准备为8.1%(3%至13%,95%CI)。本研究结果表明,对于至少有1年力量训练经验的参与者,心理准备可能会增加卧推运动中的力量产生。
